re PR tree-optimization/59747 (wrong code at -Os and above on x86_64-linux-gnu in 64-bit mode)
PR tree-optimization/59747
* ree.c (find_and_remove_re): Properly handle case where a second
eliminated extension requires widening a copy created for elimination
of a prior extension.
(combine_set_extension): Ensure that the number of hard regs needed
for a destination register does not change when we widen it.
PR tree-optimization/59747
* gcc.c-torture/execute/pr59747.c: New test.
